Abstract : The novel phenol and phthalazine-based symmetric compartmental 26-membered polyaza macropolycyclic ligand LH2, was synthesised, incorporating 2,6-diformyl-p-cresol and 1,4-dihydrazinophthalazine via 1:1 condensation. Its coordination behaviour with CuII and ZnII ions was investigated. The tetranuclear complexes [M4μ(Cl2)(L)Cl4]·2H2O exhibited aremarkably high stability, suggesting that, along with the large number of nitrogen donors available for metal binding, deprotonated phenolic functions were also involved in binding the metal ion. Incorporation of the bridging units into the macrocyclic cavity influenced electronic communications between the metal ions.
